One way is to run it through the xpeditor and then change the "values of variables" there, while the "xpeditor is executing your program". Change the value of varibale to some value which will make it to abend.

Other way is, create a test data of such a nature which will ensure an abend - make sure that data is constructed such a way that you get at least one chcek-point.

Also, check-point logics are specific to shops and for an analyst programer the main concern is "check-point frequency". Usually, there are "screens" to alter these frequencies in "test-region" - so if you are working with small-set of test data, you might like to alter the check-point frequency in order to test the logic.
